The Unlock System:

Every time you play and pass a song, you get points in the following manner:

1 Player, pass a Single mode song - 1 point
1 Player, pass a Double mode song - 2 points
1 Player, all Perfects on a Single mode song - 10 points
1 Player, all Perfects on a Double mode song - 20 points
2 Players, both pass a Single mode song - 2 points
2 Players, 1 passes and 1 fails a Single mode song - 1 point
2 Players, Both Players fail a Single mode song - 0 points
2 Players, 1 Player gets all Perfects and another passes - 11 points
2 Players, 1 Player gets all Perfects and another fails - 10 points
2 Players, both get all Perfects - 20 points

*NOTE* This applies to each song in an oni course as well. Also, passing with a grade of "D" gets you 0 points, as I have been told, anyway.

The total number of points required for the next unlock starts at 750 points, but varies due to some method for which the specifics about this are still not known, though the general consensus among players in Japan is that it is time-based (how long it takes to get the next unlock). If the next unlock is done within a set time, the machine will skip the next unlock (i.e., going from unlock 1 to 3 instead of 1 to 2). If it takes longer, the next unlock in sequence will be unlocked. If the unlock takes longer than some set time, the number of points required may even be reduced, but again, the specifics about this are not known. In the case the machine is unlocked very quickly (matters of hours between unlocks), the points required jumps from 750 per unlock for the first 15 unlocks to 1000 points for the last 15. In the case (likely) the machine has skipped an unlock during the process, after unlock 30, the unlock order cycles back to 1 and the remaining unlocks are done in sequence.

Machine Unlock Codes

If you want to speed up the unlock process so you have fewer unlocks to do, follow these instructions:

1)

Go to the operator menu, and select 'Game Options'. There will be an option that says 'Clear Machine Points'. *Warning* : This will clear all of your unlocks). Choose this option, and when it asks you to confirm it, choose yes. Now, return to the main menu.

2)

Go to 'Game Options' again, but instead of pressing the start button to enter the menu, press and hold the Service Switch and the Down arrow on the 1P side, and while holding them down, press the 1p Start Button. It should take you to the "Secret" menu
